Aman Sinha commented on DRILL-3045: ----------------------------------- Could you change the parameter DEFAULT_OFF_HEAP_ALLOCATION_IN_BYTES to DEFAULT_MAX_OFF.... to more accurately reflect the usage. Also, is there a reason these are declared public ? Seems QueryContext is the only place where they are used. > Drill is not partition pruning due to internal off-heap memory limit for > planning phase > --------------------------------------------------------------------------------------- > > Key: DRILL-3045 > URL: https://issues.apache.org/jira/browse/DRILL-3045 > Project: Apache Drill > Issue Type: Bug > Components: Query Planning & Optimization > Affects Versions: 1.0.0 > Reporter: Victoria Markman > Assignee: Mehant Baid > Fix For: 1.2.0 > > Attachments: DRILL-3045.patch > > > The symptom is: we are running simple query of the form "select x from t > where dir0='xyz and dir1='2015-01-01';" partition pruning works for a while > and then it stops working. > Query does run (since we don't fail the query in the case when we failed to > prune) and return correct results. > drillbit.log > {code} > 015-04-19 15:54:22,027 [2acc305b-8f77-09af-1376-f6475c6a23c3:foreman] WARN > o.a.d.exec.memory.BufferAllocator - Unable to allocate buffer of size 5000 > due to memory limit.
